p Application mea august 1, 1927. seriai No. 209,671.

.My invention relates to typewriters and it/ hasfparticular relation to paper supporting ymeans used in connection with the paper table e ofv a typewriting machine, such means being commonly referred to as paper fingers. More especially my invention contemplates the provisions of such paper fingers as can be very simply and expeditiously 'brought into operating position and withdrawn from 0 such position when the same are not needed. It frequently happens, in the manipulation of a typewriter, that some means is desired\to support a paper for a considerable distance above the usual paper table.

That su-ch a provision is especially required ina portable typewriter is apparent from the minimum volume requirements and the fact that the paper table must necessarily be compact and small. My invention contemplates providing the usual papertable with paper fingers which may be elevated to support the material being written upon and which, when not required for such support, may be collapsed to minimum volume or space occupying pos1t1on.

Another of the concomitant objects ofemy invention is to provide such adjustable paper fingers as may be manufactured very cheaply and applied to the portable typewriter Without material increase in the cost of the machine llas a whole. c

u Moreover, I provide a novel motion in connection with my paper fingers or supports so that the same are raised from an inoperative to an operative position with a minimum movement of the actuating means.

My invention will be betterunderstood by reference to the accompanying drawing, in

4o which: f

Figure 1 is a perspective view of as much of a typewriter as is necessary to clearly and operatively disclose my inventionthe paper supporting fingers being shown in elevated I.

or paper-supporting position; l

Fig. 2 is a rear elevational view of the paper table proper of the typewriting ma- .chine showing the fingers in collapsed posi.-

tion in full lines and in-elevated position in broken lines;

Fig. 3 is a fragmentary sectional view taken on the line 3--3 of Fig. 2; and

Fig. 4 is a fragmentary sectional View taken on the line 4-4 of Fig. 2.

In Fig. 1 I have illustrated in perspective a platen 10 mounted in end frames 11, it bein understoodthat these end frames are adapted for positioning on the carriage portion of. a typewriter in accordance with anyv desired scheme.

Mounted in the end frames' and in association with the rotatable platen is al paper table 12. In order to support a paper or other material which is being written upon in such position that an appreciable portion of the written matter may be constantly referred to, I have provided paper supporting' means in the form of fingers 13 and 14.

It is desirable and in fact essential when such fingers are used on a-portable typewriter, where it is necessary that the parts thereof occupy a minimum amount of space, that these fingers be adjustable or collapsir ble so that they do not protrude beyond the i paper table when in inoperative position.

Referring now toFigs. 2and 3, I have shown in Fig. 2 the fingers 13 and 14 in elevated position' as also in Fig. 1. The fin er 13 is pivotally mounted at 15 on a brac et 16 which is secured to the rear of the -paper table as shown. The finger 14 is mounted for pivotal movement at 17 on a similar bracket 18. 'An actuating means comprises members 19 and 20adapted to be moved by the actuation of a button 21 which is secured. to the rear edge of the paper table 12. The

' member 19 is fastened to the finger 14 at the off-center point 23, and the member 20 is4 likewise secured at the point 23 on arm 1.4 and extends around and is secured to the extended portion 24 of thearm 13 at the point 25 thereof.. By referring to Fig. 2 it will be noted that when the button 21 is moved 1ongitudinally along the rear edge or overturned portion of the paper table, the fingers 13 and 14 are collapsed into the position shown insaid Fig. 2.

Although theparts employed in my novel t arrangement are relatively few, it requires [a veryv short motion` of the actuating means 21 to raise the finger into operative position. Moreover, the parts are all. raised under the overhanging adjustment of the paper table so that they occupy the space no-rmally used for no other purpose. It will be apparent, therefore, to,those skilled in the art that I have provided a means whereby a portable typewriter may be equipped with the desirable, and in many cases necessary, paper supporting fingers, and that moreover, I have so arranged the aforesaid fingers that .it may be changed from inoperative to operative position very easily.

While, therefore, I have ldescribed but one embodiment of my invention, it is apparent that others may enlarge the same and through the employment of means which are the full equivalent of those illustrated and claimed Withoutdeparting fromthe spirit of my invention, and I desire, therefore, that my in-I vention be limited only by the showing in the prior art and the scope of the appended claims. y,

Iclaim:

In a typewriting machine, a paper table and an adjustable auxiliary paper supporting means associated with said table, the latter comprising ngers pivotally mounted for movement from inoperative to operative posia linger piece slidable alongthe upper edge tion, and'actuating means comprisin an arm having a finger piece slidable along t e upper edge of the paper table and connected to said supporting means at off-center points to'raise the latter.

2. In a typewriting machine, a paper table, two paper fingers separately pivoted on the back ofsaid table, a substantially'horizontal-ly extending connecting link pivotally connected at its respective ends to one of said fingers below the. point of pivotal support of said finger and to the other of said fingers above the pointof pivotal support thereof, and a substantially horizontally extending bperatv ing member having one end pivotally connected to one of said fingers at a point-displaced from the point of pivotal support thereof and having its other end `formed as ofsaid table to actuate said fingers. v
